Are the Nostalgic Hero Magazines all relative short? I never see/read one in real. I only have the hakosuka-book in japanese of course, but japanese pictures are comprehendible all over the world

No, these are merely select sections from some issues. Curiously. The magazines themselves are large, full of a few big features, a section or two on specific cars, a repair section, more car features, old scrap car feature, and of course a for-sale section. More than enough to keep any Japanese car fan entertained... Even if 日本語を話しません...
